The marine environment is unique and requires technologies that can use sound to gather information since there is little light underwater. In this activity, the students will be shown benthic habitat images produced by GIS. These images...

Historically, sea floor mapping occurred with a more simple data collection method: soundings. Soundings are taken by dropping a weight with a pre-measured rope off the side of the boat and noting the measurement on the rope when the...

A data rich exercise built around four global data maps to help learners discover the processes that occur at plate tectonic boundaries. The lesson is based on the jigsaw concept, mixing the students to work in different groups during...

This map details the area around the Marshall Island seamounts. Seamounts are one of many features that are found in conjunction with abyssal plains.
